"kHarper Electronic Harp with 4 strings
We built a physical version of the Karplus-Strong physical model for strings. There is a whole group of Karplus-Strong algos and we are using a bunch of them. We built 3*3 sound engines that are each producing four voices.
kHarper is easily epic and cinematic. Can do big bwaaps as well as slow and emotional chords. Unlike a banana.
4 strings Every string is a voice. The strings are built out of two touch strips with an LED bar in the middle, showing you what kHarper is doing. Each string has a knob on top to set the tone and a CV -in below. You can also patch in a gate to pluck the string.
kHarper has a very wide range of sounds. You can go from wild distorted guitars to meditative soothing plinkies. Just like any other stringed instrument there are 10.000 ways to play.
Being able to touch these Karplus-Strong models adds the natural chaos of a physical manifestation. Plucking amazing.

"The Passive Operator is a one-of-a-kind drum synthesizer that operates without the need for an external power supply. Instead, it relies on triggers, gates, and Control Voltage (CV) signals, making it compatible with Eurorack modular systems or standalone setups. Developed as part of the Tropical Noise platform, this drum synthesizer offers experimental sounds and a truly unique sonic experience. In this article, we will explore the features and capabilities of the Passive Operator, highlighting its design, functionality, and the potential for creative sound manipulation.
1. Design and Construction: The Passive Operator is housed in a sturdy bricky format box made of solid aluminum. Its robust construction ensures durability and reliability, making it suitable for both studio and live performances. The device features different compartments, each serving a specific purpose in shaping the sound.
2. Input Compartments: The Passive Operator boasts two input compartments, labeled "WTF in 2x." These inputs are located on the left side of the device and accept CV, gate, trigger, and even audio signals. The sensitivity of these inputs allows for precise control and modulation, enabling users to create intricate rhythmic patterns and dynamic soundscapes.
3. Mix Compartment: The mix compartment serves as a central hub for signal routing. By connecting the mix output to the matrix, users can explore various combinations of triggers and CV signals, resulting in unique rhythms and tonal variations. The mix compartment enhances the versatility of the Passive Operator, allowing for seamless integration with other modular gear or audio equipment.
4. Patch Matrix in and Outputs: The patch matrix provides multiple outputs for triggers and Control Voltage, expanding the creative possibilities of the Passive Operator. Users can experiment with different patching configurations, both internally within the matrix and externally to other jacks. Additionally, the matrix offers control over the potential meters, enabling users to fine-tune their sound by finding sweet spots and manipulating the tonal characteristics.
5. Customization and Expansion: One notable feature of the Passive Operator is its ability to accommodate electronica compartments. This unique design aspect allows users to swap out compartments, effectively changing the sound characteristics of the device. Furthermore, the addition of a touchpad offers an alternative control method, enabling users to interact with the synthesizer using their fingers, adding a tactile and expressive dimension to their performances.
Conclusion: The Passive Operator is a remarkable drum synthesizer that defies convention by operating without the need for external power. Its unique design, experimental sounds, and versatile functionality make it a standout option for musicians and sound enthusiasts. The combination of triggers, gates, and Control Voltage signals opens up a world of creative possibilities, allowing users to sculpt their own unique rhythms and tones. With its solid aluminum construction, intuitive interface, and the potential for customization and expansion, the Passive Operator is a must-have tool for those seeking to push the boundaries of electronic music production. Watch the demonstration video to see the Passive Operator in action and discover the endless sonic possibilities it offers.
Remember to check out the Passive Operator and experience the innovative world of drum synthesis without the need for power supply limitations. More demo www.errorinstruments.con Available from 15 December"

EXPERIMENTAL MULTI-EFFECTS
White Rabbit has REVERB and DELAY sound effects. Fall down a rabbit hole with deep sounding spatial effects. You can send your White Rabbit down different paths or take the ERROR door into other spaces. All effected by Y and the big X holding onto time.
White Rabbit is a collaboration between ERROR and TiNRS; connecting their physical and virtual spaces with crazy creativity in object and DSP.
The first switch sends the rabbit down to REVERB or DELAY holes – or sitting in the middle doing nothing.
The second switch choses Standard, Pingpong or Error DELAYS and Hall, Experimental or Error REVERBS.
DELAY
Standard –Shouting down the rabbit hole. X changes time to echo and Y the amount of feedback
Pingpong – Stereo hopping between channels. X determines the airtime of the bounce and Y keeps stacking the signal.
ERROR – Karplus-Strong algorithm plucking your signal. X is the length of the string and Y is the dampening. Set X all the way to the right and connect the output to the input to create a self-oscillating sound that you can control.
REVERB
Hall – Unexpected big space. X is the size and Y the brightness of the space.
Experimental – Cinematic shimmer. Y is pitch bending and X is the size of the space
ERROR – Like sticking your head in a metal bucket. X is the size of the bucket and Y is granular. Set X all the way to the right and connect the output to the input to create a self-oscillating sound that you can control.
The third knob is the Wet / Dry mix. To the left is dry and to the right is wet. Soaking White Rabbit.
"Introducing the Die Antwoord Apparat - a compact and versatile Lofi sampler/looper with a unique vintage charm. This standalone device features control voltage capabilities for adjusting playback speed, pitch, and filtering, making it a dynamic tool for creative sound manipulation.
With the ability to record one sample and retain it even when powered off, the Die Antwoord Apparat harkens back to the analog answering machines of the 70s, offering a nostalgic touch to modern music production. Additionally, the device can function as a filter with CV control and doubles as a LOFI microphone for capturing raw, gritty soundscapes.
Equipped with a 9V center positive power supply, the Die Antwoord Apparat is perfect for on-the-go experimentation, allowing users to record directly from the built-in microphone or through the input jack. Check out the demonstration video to see the Apparat in action and unlock a world of sonic possibilities. www.errorinstruments.com"

Solar Installation is an experimental synthesizer — a bridge between art, sound, and technology. It reimagines how we interact with music, offering a different and deeply artistic way to explore and create sounds.
At its core lies a patch bay that opens up endless sonic possibilities. By experimenting with its connections, you can discover countless “sweet spots” where unexpected textures and tones emerge. The engine itself is alive with movement, evolving harmonics, and shifting layers of sound.
An integrated effects processor lets you transform these tones even further, adding lo-fi echoes, delays, and atmospheric modulations to shape entirely new sonic landscapes.
What truly sets Solar Installation apart is its dual-mode oscillators. Each of the four oscillators can be controlled in two unique ways:
• Precision Mode – using traditional potentiometers for accurate, tactile manipulation.
• Light Interaction Mode – using highly sensitive light sensors that respond to movement and changes in illumination.
This makes the instrument behave like an interactive installation. By positioning it in different lighting environments or allowing natural shadows to play across its sensors, the machine evolves on its own, creating ever-changing, generative music.
Sometimes, it behaves like a futuristic music box — a self-driven system producing evolving patterns, unexpected harmonies, and “happy accidents.” It invites you to let go of control and embrace the beauty of randomness, where sound becomes an organic, living experience.
Solar Installation exists between instrument and sculpture, science and art, intention and chaos. It’s not just about making music — it’s about exploring possibilities.
